drm: introduce drm_dev_{get/put} functions

2018-04-19T04:10:22+00:00

Reference counting functions in the kernel typically use get/put suffixes. For maintaining coding style consistency, introduce drm_dev_{get/put} functions. All callers of drm_dev_ref() API have been converted in this patch and hence it has been dropped while the drm_dev_unref() API with non-trivial number of users remains for compatibility. The semantic patch scripts/coccinelle/api/drm-get-put.cocci has been updated with the new helper for conversion of drm_dev_unref() to drm_dev_put() Signed-off-by: Aishwarya Pant Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/6babda56134035a98220d5d37a4fd4048df214ce.1506413698.git.aishpant@gmail.com (cherry picked from commit 9a96f55034e41b4e002b767e9218d55f03bdff7d) Signed-off-by: Joel Stanley

drm: Introduce drm_property_blob_{get,put}()

2017-02-28T15:16:46+00:00

For consistency with other reference counting APIs in the kernel, add drm_property_blob_get() and drm_property_blob_put() to reference count DRM blob properties. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. A semantic patch is provided that can be used to convert all drivers to the new helpers.

drm: Introduce drm_gem_object_{get,put}()

2017-02-28T15:16:43+00:00

For consistency with other reference counting APIs in the kernel, add drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked variant of the latter, to reference count GEM buffer objects. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. The existing semantic patch for the DRM subsystem-wide conversion is extended to account for these new helpers.

Coccinelle: misc: Add support for devm variant in all modes

2016-12-11T11:08:26+00:00

Add missing support for the devm_request_threaded_irq in the rules of context, report and org modes. Misc: ---- To be consistent with other scripts, change confidence level of the script to 'Moderate'. Signed-off-by: Vaishali Thakkar Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: misc: Improve the result given by context mode

2016-12-11T11:08:26+00:00

To eliminate false positives given by the context mode, add necessary arguments for the function request_threaded_irq. Signed-off-by: Vaishali Thakkar Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: misc: Improve the matching of rules

2016-12-11T11:08:26+00:00

Currently because of the left associativity of the operators, pattern IRQF_ONESHOT | flags does not match with the pattern when we have more than one flag after the disjunction. This eventually results in giving false positives by the script. This patch eliminates these FPs by improving the rule. Signed-off-by: Vaishali Thakkar Signed-off-by: Michal Marek

Coccinelle: Add misc/boolconv.cocci

Add a script to check for unneeded conversions to bool. Signed-off-by: Andrew F. Davis Acked-by: Julia Lawall Signed-off-by: Michal Marek
